Borg
Deduplicating archiver with compression and encryption. BorgBackup (short Borg) gives you space-efficient storage of backups. Secure, authenticated encryption. Compression, LZ4, zlib, LZMA, zstd (since borg 1.1.4). Mountable backups with FUSE. Easy installation on multiple platforms, Linux, macOS, BSD. Free software (BSD license). Backed by a large and active open source community. Optionally, it supports compression and authenticated encryption. The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to not fully trusted targets. Deduplication based on content-defined chunking is used to reduce the number of bytes stored: each file is split into a number of variable length chunks and only chunks that have never been seen before are added to the repository.

Plakar
Plakar is the open backup platform enabling resilience-as-code for security and infrastructure teams. A declarative last line of defense built around Kloset, an immutable encrypted deduplication engine that collapses the encryption-vs-efficiency tradeoff and makes complete coverage affordable, paired with a Kubernetes-native control plane that lets teams define, orchestrate, and verify resilience policies as code across VMs, databases, K8s workloads, object storage, and AI pipelines. When ransomware hits, an AI agent breaks production, or you need to walk away from a cloud provider, your data stays portable and recoverable. Plakar runs a zero-trust resilience layer on infrastructure you own — declaratively governed, agent-ready, and priced so complete coverage is actually achievable. Your keys. Your data. Your recovery path.
